ROLLER FOR LOOM-'TEMPLE'.S.

SPECIFICATION forming part of Letters Patent No. 255,689, dated March28, 1882.

Application ined May 10,1880. (No model.)

To ail whom it may concern.-

Be it known that I, JOHN B. S'IAMOUR, a subject of the Queen of GreatBritain and Ireland, residing in Philadelphia, Pennsylvania,

have invented an Improved Roller for Loom- Temples, of which thefollowing is a specification.

The object of my invention is to make a roller for loom-temples whichwill possess the quali- Io ties of strength, lightness, and durability,and in which the pins will be firmly retained; and this object I attainin the manner hereinafter set forth, reference being had to theaccompanying drawings, in whichi Figure l is a perspective view of myimproved roller for loom-temples in the form which I prefer; Fig. 2, atransverse section of 'the same; Fig. 3, a longitudinal section; Fig. 4,a diagram illustrating` one of the features 2o of the invention; andFigs. 5, 6, and 7, views of modified forms of the roller.

The roller shown in Figs. I, 2, and 3 conlprises an outer tube orcasing, a, a central tube, b, an intervening tube, r1, and pins e,

z5 which are driven through the outer casing, a, and into the tube d, asshown in Figs. a and 3. The tubes a and b are made of metal; but thetube d, I makeof-the substance known as vulcanized ben7 as I have foundthatthis 3o substance takes--a very rm hold of the pins e,

and possesses the desirable qualities of lightness, toughness, anddurability. The sub stance, moreover, is not affected by moisture or byextremes oftemperature to such an extent as to cause it to split or toexpand and contract sufficiently to injure the tubes a. and b, orinterfere with the proper hold of said tubes on the tube d or of thelatter upon the pins e. Before driving the pins e into thc roller, open-4o ings are made in the same for the reception of the shanks of saidpins, and these openings I prefer to make ofthe character shown in Fig.4.-, on reference to which it will be' observed that that portion of theopening which is in the casing a is slightly ilarger than the shank ofthe pin, while that portion of the opening which is in the tube d isslightly less than said shank.

The pins can be readily driven into an openpin is securely retained inits proper position.'

That portion ofthe opening which is within the casing a may bejust equalin diameter to the shank of the pin, instead of being larger than thesame; but the latter plan is the most desirable one.

The outer tube or casing, a, imparts to the roller a neat appearance andpresents a good Wearing-surface, and the inner tube, b, which is adaptedto the pin of the temple, provides a bearing which, when worn, can bereadily removed and replaced by a new one, thus obviating the necessityof furnishing an entirely new roller when the bearing becomes worn. Theuse of the casing a and tube b, however, are not essential to myin'ventioma's a serviceable roller may be made of the vulcanized fiberalone, as in Fig. 5; or the roller may have the outer casing only, as inFig. G, or. the inner tube only, as in Fig. 7. It is preferable,however, for the reasons above set forth, to construct thc roller asshown in Figs. l, 2, and 3.

I do not desire to claim broadly a templeroller consisting of an outercasin g of metal, an inner core of other material, and pins driventhrough the casing and into the core, as such rollers have been proposedprior to my invention; but

I claim as my invention and by Letters Patent- A temple-roller having acore or bodyot vulcanized tiber,into openings in which 'the pins aredriven, and by which said pins are retained, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

desire to secure JOHN B. STAMOUR.
